I've had MC for awhile now, but never registered until now. I just got it back shortly before the newest update and everything is fine. But now when I try to play the latest version, I can't. The launcher is slow loading the game, and when I tried to play on an old save it wouldn't work. So I try to make a new world to try and see the new stuff. This is the error report I got

I've also gotten an error that says it can't load the bit from FM or something. I have updated my drivers and gotten the latest version of Java, so I've no idea what's wrong :/

This is caused by your Antivirus or Firewall

You need to create a rule that will cause whichever one is blocking java from the network to stop doing it.

Okay, so I tried joining a Zhorde server that was updated to 1.7 and it works. Seems that I can't just make my own single player worlds. Something about an internal exception class "blah blah blah" cannot render from FM.

I fixed the issue with the anti-virus breaking MC.

I also already wiped the old minecraft folder and downloaded the exe from the site again. So the problem's halfway fixed, I just don't know what's causing the internal exception error :/
